摘要
泵类设备在核电厂流体输送系统中扮演着重要角色,是确保系统顺畅运作的关键。核电厂运行环境特殊,包括极端高温、高压以及高放射性水平,对泵类设备的稳定运行和可靠性提出了严苛要求。人工巡检的可达性较差,导致泵类设备在此环境中发生故障的频次相对较高。本文选取泵类设备中常见的故障模式——碰摩故障,通过收集和分析行业内数百台泵组运行数据,结合机械部件在实际工作中的运行特点,提出了故障机理模型,以此分析故障发生的影响因素和故障信号特性,并对故障机理和试验数据进行深入分析,为后续的特征提取与故障诊断提供了重要指导。
The pump equipment plays an important role in the fluid conveying system of nuclear power plant and is the key to ensure the smooth operation of the system.The operating environment of nuclear power plants is special,including extreme high temperature,high pressure and high radioactivity level,which puts forward strict requirements for the stable operation and reliability of pump equipment.Due to the poor accessibility of manual inspection,the frequency of pump equipment failure in this environment is relatively high.In this paper,the common fault mode rubbing fault in pump equipment is selected.By collecting and analyzing the operation data of hundreds of pump sets in the industry,combined with the operation characteristics of mechanical components in actual work,a fault mechanism model is proposed to analyze the influencing factors of fault occurrence and fault signal characteristics.The fault mechanism and test data are analyzed in depth,which provides important guidance for subsequent feature extraction and fault diagnosis.
